Ted, I have an Ambassador and bought a foam kit from Ebay. It came with three pieces. The eggcrate for the top and two pieces for the bottom. The top looks to be a couple inches from the tips of the points to the bottom of the pad. The tips are almost flush with the edges of the top. The other pieces are a little over 1/2" thick. I like the versatility of being able to take out foam as needed. For the big herfs I take out all the foam and just load it with fivers. For a normal one day affair I use the top and a single bottom piece.
